Description

Technical Field

[0001] This invention relates to the field of polishing technology, and more particularly to a polishing head. Background Technology

[0002] In industrial production, surface treatment and other fields, grinding is a key step in achieving a smooth and flat material surface and is widely used in metal processing scenarios.

[0003] Chinese patent CN221247208U discloses a polishing device, which includes a base, an adjusting component, a brush cylinder, and a driving component. The base has an adjusting groove, and the adjusting component is connected to the base and can slide along the adjusting groove. A gear is rotatably connected to the adjusting component, and the brush cylinder is rotatably connected to the base. The brush cylinder is used to remove burrs from the gear. The adjusting component can move the gear closer to or away from the brush cylinder, and the driving component is connected to the brush cylinder and drives it to rotate. The adjusting component moves the gear closer to or away from the brush cylinder, allowing gears of various sizes to contact the brush cylinder, facilitating burr removal. Therefore, the polishing device can be applied to gears of various sizes and specifications.

[0004] However, most of these devices use a single brush disc structure, where the brush disc can only rotate in a fixed direction. This limits their effectiveness in treating complex surfaces or stubborn stains, and can easily lead to problems such as grinding dead corners or localized over-grinding. Although some devices use a multi-brush disc design, the brush discs rotate in the same direction, which can easily create mutual interference forces between adjacent brush discs, thus reducing the grinding accuracy.

[0005] Therefore, a grinding head needs to be developed to solve the above problems. Utility Model Content

[0029] Please refer to Figures 2 to 3 The polishing brush 3 includes a brush box 31, a positive brush assembly 32 and a negative brush assembly 33 disposed in the brush box 31, and a brush body 34 mounted on the positive brush assembly 32 and the negative brush assembly 33.

[0030] The brush box 31 is fixedly connected to the outer shell 22. It includes an upper box 311 and a lower box 312. The upper box 311 and the lower box 312 are recessed from opposite sides to form a receiving cavity 313. The positive brush plate assembly 32 and the negative brush plate assembly 33 are both installed inside the receiving cavity 313. The end of the transmission rod 21 and the transmission gear 23 pass through the upper box 311 and extend into the receiving cavity 313, cooperating with the positive brush plate assembly 32 and the negative brush plate assembly 33.

[0031] Please refer to Figure 3 Specifically, the positive brush assembly 32 includes a positive connecting shaft 321, a positive brush gear 322 located at one end of the positive connecting shaft 321, and a brush body 34 located at the other end of the positive connecting shaft 321. The positive connecting shaft 321 is connected to the lower box 312 through a bearing. One end of the positive connecting shaft 321 that is sleeved with the positive brush gear 322 is located in the receiving cavity 313, and the other end that is connected to the brush body 34 extends out of the lower box 312. The positive brush gear 322 meshes with one of the transmission gears 23 of a pair of transmission gears 23.

[0032] The reverse brush assembly 33 includes a reverse connecting shaft 331, a reverse brush gear 332 located at one end of the reverse connecting shaft 331, an intermediate connecting shaft 333 located on one side of the reverse connecting shaft 331, and an intermediate gear 334 located at one end of the intermediate connecting shaft 333.

One end of the reverse connecting shaft 331, which is sleeved on the reverse brush gear 332, is located inside the receiving cavity 313, and the other end is connected to the brush body 34. One end of the brush body 34 extends out of the lower box 312. The intermediate connecting shaft 333 is installed inside the receiving cavity 313, and its bottom is fixedly connected to the lower box 312. The intermediate gear 334 is placed inside the receiving cavity 313 and meshes with the reverse brush gear 332 and the other drive gear 23 of a pair of drive gears 23.

[0033] More specifically, the teeth of the positive brush plate gear 322 and the negative brush plate gear 332 are in opposite directions, and the brush plate body 34 driven by the positive brush plate assembly 32 and the brush plate body 34 driven by the negative brush plate assembly 33 rotate in opposite directions.

[0036] When the grinding head of this utility model is in use, after the drive component 1 is started, its output end drives the transmission rod 21 in the transmission assembly 2 to rotate. At this time, a pair of vertically arranged transmission gears 23 at the end of the transmission rod 21 rotate synchronously with the transmission rod 21. The transmission gears 23 respectively engage with the gears of the positive brush plate assembly 32 and the negative brush plate assembly 33 to achieve power distribution. One of the transmission gears 23 meshes with the positive brush plate gear 322, driving the brush plate body 34 at the end of the positive connecting shaft 321 to rotate forward. The other transmission gear 23 meshes with the intermediate gear 334, which in turn meshes with the negative brush plate gear 332, ultimately driving the negative connecting shaft 331 to rotate, causing the brush plate body 34 at the end of the negative connecting shaft 331 to rotate in reverse. The rotation drive 41 is activated, driving the drive gear 42 to rotate. The drive gear 42 meshes with the driven gear 43, and the driven gear 43 is fixedly connected to the brush box 31. Therefore, the power is transmitted to the brush box 31, driving the positive brush plate assembly 32, the negative brush plate assembly 33 and the two brush plate bodies 34 inside to rotate as a whole, expanding the grinding coverage area.
